Thanks Bozo,
Why did your DIY scrubber not work?
I Ghetto tested stanley blower by sealing thick plastic over door sealed with tape.Cut 6" hole and stuck duct from stanley intake side(suction) and peeled tape and plastic right off the wall.

I am in woodworking stage right now.Everything cut, now to assemble.I figure i'll have to do some experiments to get it perfect.

Pics were great.That's the stuff I'm looking for.
